'To ctZ.u1hom it 71mg concern:

ments in Universal Couplings, of which the following is a specification, reference being had therein fto the accompanyin f drawings.

My invention relates tonew an useful imJ i proveniente in universal couplings7 and more particularly in the novel construction and ar rangement of parts as will be more uy hereinafter described, and set forth in the claims.

One object of my invention is to produce a sim le and accessible universal couping in which the bearings can be cheapiy and easily replaced.

Another ob'ect is to rotect the bearings fromv dust an to provi e for the storage of sucient lubricant to automaticall)T supply the bearings fora long period.

' from each furcation. Bearings for the trlm-l nions are contained in segmental In the drawings, Figure 1 shows a lon itudinal central sectionthrough the coup-ing, with one shaft-h ad in elevation. Fig. 2 1s an end view take on sectiondine 2 2 of Fig. l1, and Fig. 3 is ai perspective of oneof the segmental blocks? A and B are tlle shaft-heads or knuckles, which I have shdwn keyedvon the shafts C and C by means d'f keys c; but it is obvious that the may be forged inte'ral with the shafts, desired. The end o each shaft.u head is bifurcated or notched and provided with a trunnion D, projecting transversely blocks S, which are apertured, re e ab centrally at s, to receive them. ch bloc is 'substantially a quadrant, fso that when laced together with ends abutting they orm a com lete circle. In this position the)T yare incios A Eend are' held from eteral movement the inwerdly-extending ange F on one si e of the Etasin and the annular nut G'on the other sid fof tigre casing. The nutG is provided Wit apertures g to receive the ends of a span ner, and its pe i hery has a screw-threaded en agement wit the interior of the casing E. o form space for grease or other lubrw ant,

acin 'f in a snuly-tting annular casing.

I eut away a portion ol the outer side of each block adjacent to thc bearinvr to iorin the space II between the block andthe casing.

VVitii this construction each bearing isin a separate block and "when worn or broken may be easily and cheaplY replaced b a new block. By removing the nut G the W ole device may" be easily,r diei-mounted, and when necessary the space H may be iilled with grease or other lubricant. The casing is dustproof, for the reason that the parte may be tightly locked together by the nut G, and for; the same reason the lubricant will be retained for a lon period.

What I claim as my invention ism 1. In a universel coupling, the combination with a pair of shaft-headsJ of trunnions thereon, se mental blocks containing bearings for sai trunnions, and Va easing and nut inciosing said blocks, substantially as de- ,h scribed,

2. In a universal coupling, the donibina tion with a pair of shaft-heads, of trunnions thereon, s mental blocks containing bearings for sai trunnions, an annular casing in` closin said blocks, there being an inwardly-` exten 'ng flange on one side of said casing and a nut en aging the other side, for the purpose desem ed.

3. In a universal coupling the combination with va pair ofshaft-heads, of trunnions thereon, se mental blocks apertured for bearings for sei trunnions, an annuler casing and e nut therefor inclosing said blocks, ortions of the blocks adjacent to the ends of t ie irun; :lions bein out away to form lubricant-state," substantie ly as described.

tion with apair of shafts, of trunnions on the ends thereof, the a rtured segmentieces S, and a housing t erefor, substantialy as and for the purpose described, l

5. In a'universal coupling the combinetion with a pair of shaft-heads, of trunmons thereon, segmental biocks each eontainin the bearings for one of said trunnions, sai blocks having abutting ends and together ormin a com lete circle, and retaining means Ier said'b ocks. Y

6. In a universal couplin the combina` tion with a pair of shaft-hea s, of trunnions thereon, spacing-blocks for said trunnions,

4. In a universal' coupling, the combina- 9o fr do and an integral annular casing retaining said blocks, portions of said blocks being spaced from said casing, for the urpose described.

7. In a universal coup ing, the combinationfwith a pair of shaft-heads, of "a pair of oppositely-dxeposed trunnions on each head, a separate block for each trunnion containing bearings therefor, said blocks having abutting ends and retaining means inclosmg said blocks, substantiall as described.

8. In a universe. joint the combination with a pair of shaft-heads and oppositely-extending trunnions on said heads of quadrantblocks, each block containing t e bearing for one of said trunnionsj and an integral annu- Y lar casing for holding said blocks end to end.

9. In a universal .joint the combination with an annular casing, of a plurality of intersemana changeable blocks abuttin' end toendin said with a pair of shafts having -ends and oppo.

sitely-extending trunnions on each of said ends, of a plurality of abutting blocks each having the entire bearing for one of said trunnions, and retaining means for said blocks, substantially as described.

In testimony whereof I affix .my signature in presence of two witnesses.
